I have not seen a Silhouette Romantic Suspense (or whatever they are called in the UK/Australian area) in... almost a year. I see plenty of Harlequin Mills & Boon Modern (the UK/Australian "Presents" counterpart) and the occasional Blaze, but never the Romantic Suspense ones.
I guess the SEALs, FBIs, and what not are deemed by Harlequin as of limited interest to romance readers outside the USA?
